As per our Shipping and Returns Policy, custom cuts and fabricated parts are non-returnable. If you need an over- or undersized item, note it under "Comments" during Checkout. Cut-to-size orders have an acceptable cut tolerance of 1/8" (0.125"), so clarify if the adjustment is to be made on the (+) or (-) side of the saw blade.Please review our full return and shipping policy here.
Measure Twice, Cut Once
Since custom cuts and fabricated parts are non-refundable, be very careful while measuring your dimensions. As each cut is nominal, even the slightest miscalculation could be costly.
How to Use a Measuring Tape
Extend your tape measure several inches to find the 1 and 2 inch markers. In between the inch markers you’ll find 16 equally spaced tick marks.
Measure by counting the increments beyond the nearest inch. As the increments decrease, so does the length of the mark. For example, 1/2" has a bigger mark than 1/4" which has a bigger mark than 1/8". The smallest mark follows at 1/16". Please be aware that some measuring tapes may have even smaller increments.
Features of a Measuring Tape: Sliding End Hook
The sliding end hook is designed for two different types of measurements. An outside measurement (where the hook of the tape hangs over an edge), requires the hook to slide out a bit to account for the thickness of the material. When making an inside measurement (where the hook will push up against a surface), the clip slides in, again, accounting for its thickness. The measuring tape self-adjusts to guarantee an accurate measurement (as far as the tape is concerned).
Sanitizing Acrylic and Polycarbonate Sheet [X]
Acrylic and Polycarbonate Sneeze Guards and like products require special care while cleaning and disinfecting. To maintain the optical clarity of sneeze guards and other acrylic or polycarbonate items, use an acrylic or polycarbonate safe cleaner like Novus Plastic Polish #1, Brillianize Plastic Cleaner, or a mild soap solution.
Please reference the following compatible cleaners when DISINFECTING acrylic and polycarbonate items. The use of commonly available commercial alcohol or ammonia-based disinfectants may cause crazing and damage.
Cut-to-size is available for certain thicknesses. Please call (888) 768-5759 for pricing.
Machine grade Polycarbonate engineering plate features extremely high impact strength, outstanding dimensional stability, and the lowest internal stress and inclusion levels when compared to any other products in its class. The lower internal stress and reduced inclusion levels of this polycarbonate will save you time and money by reducing your fabrication process. Machine grade Polycarbonate is an excellent material for prototyping parts before injection molding.
Polycarbonate is a versatile, tough plastic used for a variety of applications, from bulletproof windows to compact disks (CDs).
It comes in transparent and opaque varieties. The main advantage of polycarbonate over other types of plastic is unbeatable strength combined with light weight. Polycarbonate is much lighter than glass, and is nearly unbreakable. Bullet-resistant variations are available and are used in windows and enclosures usually seen inside banks are often made of polycarbonate.
Virtually unbreakable with extreme impact resistance
High dielectric strength
Easily machinable
Transparent up to 2" thick
Wide temperature operating range (-40°F to 280°F)
Lightweight

Polycarbonate sheets are hard-coated, abrasion and mar resistant materials that offer a higher degree of scratch resistance and surface hardness. These materials provide superior protection against unforeseen chemical attack.
In order to prolong the service life of your polycarbonate products, using compatible household cleaners is recommended. The use of abrasive cleaners and applicators should be avoided to eliminate the possibility of surface scratching or coating.

Wow! Blown away by the easy ordering process, but more so an amazing product. Machine grade offers so much more than regular polycarb sheet. Thanks to all who helped guide us on our material choice. Interstate Plastics proved very helpful.

I was surprised by the timely manner the polycarb was delivered. We will use Interstate Plastics again the next time we have plastic needs.
